An electronic asthma screening questionnaire (ASQ) using video and touchscreens improved accuracy and satisfaction for parents with limited health literacy or English proficiency. This technology can help reduce healthcare access barriers.
Area of Science:
- Health Informatics
- Pediatric Asthma Management
- Health Literacy Research
Background:
- Low health literacy is a key factor in poor asthma control.
- Information technology (IT) can improve healthcare equity and reduce disparities.
- Addressing limited English proficiency and health literacy is crucial for effective pediatric asthma care.
Purpose of the Study:
- To design and evaluate an interactive, computer-based questionnaire for assessing childhood asthma symptoms.
- To assess the usability and effectiveness of an electronic asthma screening questionnaire (ASQ) for parents with limited health literacy and/or limited English proficiency.
Main Methods:
- Randomized controlled trial comparing electronic (tablet-based, video, touchscreen) and paper-and-pencil versions of the ASQ.
- Participants chose their preferred language (English or Spanish).
- Reliability assessed by comparing self-assessments to a nurse-guided interview (gold standard); usability and satisfaction also measured.
Main Results:
- The electronic ASQ showed significantly higher concordance with the nurse interview (68%) compared to the paper ASQ (54%).
- Parents using the electronic ASQ reported high satisfaction (100%) and ease of use (96%).
- Participant demographics included a majority of Spanish-speaking Hispanic mothers with limited education and income, highlighting the need for accessible tools.
Conclusions:
- Interactive IT tools, like the electronic ASQ, can effectively assess asthma symptoms at a manageable cost.
- This technology has the potential to overcome barriers related to English proficiency and health literacy.
- Implementing such tools can improve access to care and asthma management for underserved populations.

Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
